but each hz[i] is a 1 variable function, not a number!

what is the meaning of 'CURVES(op(j,C),op(-1,C)),op(2,P)'? 

from where i can find a full help about it?

how u calculate where the 'y' changes its sign and is imaginary or real?

thanks.

now how is possible to obtain roots of 'y' for a spacial lambda?

do i have to use 'Student[calculus1]' and then 'Roots' ? it takes a long time!

i do that, right click on a plot and copy it, but when paste it in another location just a border of a plot will appear!!

i said that i dont have any code of that plot to re-run it to reproduse it again. i just saved a plot without it's programing coeds. just a plot in a page. now when rigth click on it and want to add vertical axis label, it is possible just to write harizontally.

but i used it and plotted it. it works for me. albeit mine is with indices not []. [] is because of copy and paste here. hhz := piecewise(x < x[1], hz[1], x[1] < x < x[2], hz[2], x[2] < x < x[3], hz[3], x[3] < x < x[4], hz[4], x[4] < x < x[5], hz[5], x[5] < x < x[6], hz[6], x[6] < x < x[7], hz[7], x[7] < x < x[8], hz[8], x[8] < x < x[9], hz[9], x[9] < x < x[10], hz[10]); however if i have: {hz1 x < x1 hhz := {hz2 x1 < x x < x2 {hz3 x2 < x x < x3 {hz4 x3 < x x < x4 {hz5 x4 < x x < x5 {hz6 x5 < x x < x6 {hz7 x6 < x x < x7 {hz8 x7 < x x < x8 {hz9 x8 < x x < x9 {hz10 x9 < x x < x10 is there any way to write that exp. in brief?

i want to convert "f=0" to a polynomial in terms of "zin", like:

 a*zin^2+b*zin+c=0

so then how can i get it's coefficients?
